1.设计表

2.javabean

packagecom.cir.bean;public classUser {private intid;privateString username;privateString password;private intpermissionId;private intstatus;privateString position;public intgetId() {returnid;

}public void setId(intid) {this.id =id;

}publicString getUsername() {returnusername;

}public voidsetUsername(String username) {this.username =username;

}publicString getPassword() {returnpassword;

}public voidsetPassword(String password) {this.password =password;

}public intgetPermissionId() {returnpermissionId;

}public void setPermissionId(intpermissionId) {this.permissionId =permissionId;

}public intgetStatus() {returnstatus;

}public void setStatus(intstatus) {this.status =status;

}publicString getPosition() {returnposition;

}public voidsetPosition(String position) {this.position =position;

}

}

packagecom.cir.bean;//公文信息

public classDoc {private intid;private String tipplace; //副厂长审核意见位置

private String tipfplace; //厂长审签意见位置

private int deletestaus; //公文的删除状态

private int callback; //该公文回执信息的接受状态

privateString title;private String owner;//发送者

privateString receiver;privateString time;private int status; //流转状态

private intresult;publicString getTitle() {returntitle;

}public voidsetTitle(String title) {this.title =title;

}publicString getOwner() {returnowner;

}public voidsetOwner(String owner) {this.owner =owner;

}publicString getReceiver() {returnreceiver;

}public voidsetReceiver(String receiver) {this.receiver =receiver;

}publicString getTime() {returntime;

}public voidsetTime(String time) {this.time =time;

}public intgetStatus() {returnstatus;

}public void setStatus(intstatus) {this.status =status;

}public intgetResult() {returnresult;

}public void setResult(intresult) {this.result =result;

}publicString getPlace() {returnplace;

}public voidsetPlace(String place) {this.place =place;

}private String place; //公文存储位置

public intgetId() {returnid;

}public void setId(intid) {this.id =id;

}publicString getTipplace() {returntipplace;

}public voidsetTipplace(String tipplace) {this.tipplace =tipplace;

}publicString getTipfplace() {returntipfplace;

}public voidsetTipfplace(String tipfplace) {this.tipfplace =tipfplace;

}public intgetDeletestaus() {returndeletestaus;

}public void setDeletestaus(intdeletestaus) {this.deletestaus =deletestaus;

}public intgetCallback() {returncallback;

}public void setCallback(intcallback) {this.callback =callback;

}

}

packagecom.cir.bean;//用户权限

public classPermission {private intid;private intpermission;public intgetId() {returnid;

}public void setId(intid) {this.id =id;

}public intgetPermission() {returnpermission;

}public void setPermission(intpermission) {this.permission =permission;

}

}

2.工具类

packagecom.cir.util;importjava.sql.Connection;importjava.sql.DriverManager;importjava.sql.SQLException;public classDBUtil {//数据库连接地址

private static String URL = "jdbc:mysql://localhost:3306/test?useSSL=false&serverTimezone=UTC";//数据库用户名

private static String UserName = "root";//数据库密码

private static String Password = "18735";public staticConnection getConnection()

{ Connection Conn=null;try{

Class.forName("com.mysql.cj.jdbc.Driver");

System.out.println("加载驱动成功");

}catch(ClassNotFoundException e) {//TODO Auto-generated catch block

e.printStackTrace();

}try{//通过DriverManager类的getConenction方法指定三个参数,连接数据库

Conn =DriverManager.getConnection(URL, UserName, Password);

System.out.println("连接数据库成功!!!");//返回连接对象//return Conn;

}catch(SQLException e) {//TODO: handle exception

e.printStackTrace();

}returnConn;

}

//还应涉及对数据表的操作

}
